Induction of logic programs with more than one recursive clause by analyzing saturations
説明
This paper describes a bottom-up ILP algorithm called MRI, which induces recursive programs with one or more recursive clauses from a few of examples. It analyzes saturations using path structures, which express streams of terms processed by predicates and was originally introduced by Identam-Almquist. We introduce extension and difference of path structures. Recursive clauses can be expressed as a difference among path structures. The paper also shows experimental results.
